A Jurisdictional Determination Request Form is how you ask the U.S. Army Corps of Engineers to tell you, in writing, whether streams, wetlands, or other water features on your property fall under federal Clean Water Act authority. You download the form from your local Corps district, attach maps and site data, indicate whether you want an approved or preliminary determination, sign the right-of-entry authorization, and send the package to the district office covering your property. There is no fee.
What the Form Gets You
The Corps uses your submission to decide whether specific features on your parcel qualify as “waters of the United States.” If they do, you need a Section 404 permit before placing fill in or near them. If they don’t, those areas are outside federal permitting authority. The determination letter you receive at the end of the process is what you rely on when planning construction, buying land, or documenting the status of a site for a lender or agency.
Decide Which Type of JD You Want Before You Fill Anything Out
The form asks you to choose between an approved JD and a preliminary JD. That choice shapes what the Corps produces and what you can do with it, so make it deliberately.
An approved JD is a definitive, legally binding document that states whether waters of the United States are present and maps their exact boundaries on your property. It is valid for five years from the issue date. Because it is a final agency action, you can appeal the findings if you disagree. This is the right choice when you need certainty — before a major purchase, a long-term development plan, or a conservation transaction.
A preliminary JD is advisory. It identifies where potential waters and wetlands appear to be on the property but does not make a binding legal call. Instead, it assumes the features are regulated and lets the applicant move on to permitting on that basis. A preliminary JD cannot be appealed. Developers who already plan to avoid or mitigate wetland impacts often prefer this route because it skips the deeper analysis and gets them into the permit process sooner.
One point worth knowing before you start: if you already hold a Section 404 permit tied to an approved JD, that delineation remains valid for the life of the permit, even past the standard five years. If you obtain a time extension under 33 CFR 325.6(d) before the permit expires, the JD rides along with the extension.
Assemble Your Attachments First
The single biggest cause of delay is a request that arrives missing information. The project manager has to stop and come back to you before any real review can begin. Pull everything together before you open the form.
- Property location data. Street address, county, state, and GPS coordinates in decimal degrees. For a linear project such as a pipeline or road, provide the center point of the alignment.1U.S. Army Corps of Engineers. Jurisdictional Determination JD Form
- Survey or plat map. An accurate depiction of the parcel boundaries and the specific review area. Include township, range, and section if available.
- Vicinity map. A broader-scale map showing the property in relation to nearby roads, towns, and water features.
- USGS topographic maps. These show streams, rivers, and elevation contours the Corps uses to interpret surface water flow.
- National Wetlands Inventory maps. Free from the U.S. Fish and Wildlife Service. They are a starting point, not the final word — the Corps may identify features not shown on NWI.
- NRCS soil data. Soil survey information identifies hydric soils, which are strong indicators of wetland conditions.
- Wetland delineation report, if you have one. A report prepared by an environmental consultant using the Corps’ wetland delineation manual gives the project manager technical evidence to verify against during the site visit. A professional delineation typically costs several thousand dollars or more depending on site size and complexity, but it can materially speed up the review.
Fill Out the Request Form
The standard form is titled “Request for Corps Jurisdictional Determination (JD)” and appears as Appendix 1 to the Corps’ Regulatory Guidance Letter 16-01.2U.S. Army Corps of Engineers. Regulatory Guidance Letter 16-01 – Jurisdictional Determinations Some districts publish their own regional version with additional fields or a checklist attached, but the substance is the same. Download the form from your local district’s regulatory page.
Property Owner and Agent Information
The first block asks for the property owner’s name and contact details. If you are not the owner — a consultant filing on a client’s behalf, or a prospective buyer investigating a parcel — complete the agent/consultant fields and identify your relationship to the property. Check the box that describes your status: current owner, prospective purchaser, or authorized agent.3U.S. Army Corps of Engineers. Request for Corps Jurisdictional Determination (JD) / Delineation
Site Details and Type of JD Requested
Enter the street address, city, county, state, acreage of the review area, and decimal-degree coordinates. Indicate whether you want an approved or preliminary JD. In the “nature of the request” field, describe why you need the determination: a planned residential subdivision, a commercial site, a conservation easement, or clarification of jurisdiction before a property transaction. List every map, survey, and report you are attaching so the administrative record is complete on the day it arrives.
Right-of-Entry Signature
Your signature on the form grants Corps personnel permission to enter the property and conduct a site investigation. By signing, you affirm you have the authority to allow that access and hold the property rights needed to request the JD.1U.S. Army Corps of Engineers. Jurisdictional Determination JD Form If you cannot grant right of entry — for instance, as a prospective buyer without an access agreement — the Corps may not be able to process the request until that access is arranged.
Submit the Package to the Right District
Send the completed form and attachments to the Corps district with regulatory authority over the property. If you don’t know which one that is, the Corps maintains a district boundary lookup at regulatory.ops.usace.army.mil/offices where you can search by location.
Many districts accept electronic submissions through the Corps’ Regulatory Request System at rrs.usace.army.mil. Mail and in-person delivery remain options at districts that have not fully transitioned to digital intake. Check your district’s regulatory webpage for the preferred method; some still require wet-ink signatures on the right-of-entry authorization. There is no fee to request a jurisdictional determination.
What Happens After You Submit
Once the district receives your request, a project manager is assigned. The manager reviews your maps, aerial photography, remote sensing data, and any delineation report you supplied. In most cases a site visit follows so the manager can verify field conditions against the documentation.
There is no guaranteed timeline. The Corps prioritizes permit applications over standalone JD requests, so how long it takes depends on district workload and staffing.4United States Army Corps of Engineers. Jurisdictional Determination (JD) Form If a permit is likely at the end of the road, request the JD well before your construction window closes in. When the review is complete, the Corps issues a formal determination letter identifying the jurisdictional status of each aquatic feature on the property.
If You Disagree With an Approved JD
Only approved JDs can be appealed. Preliminary JDs carry no appeal rights; if you receive one and disagree with what it says, the remedy is to request an approved JD instead.5U.S. Army Corps of Engineers Philadelphia District. Jurisdictional Determinations
To appeal an approved JD, submit the Request for Appeal form (Section II of the Notification of Administrative Appeal Options) to the division engineer within 60 days of the date on the Corps’ notice. Miss that deadline and you accept the determination and waive appeal rights.6U.S. Army Corps of Engineers (South Pacific Division). Notification of Administrative Appeal Options and Process and Request for Appeal
The appeal is limited to the existing administrative record. Neither you nor the Corps can introduce new information. You may submit additional material only to point out where evidence already in the record supports your position. That is why the strength of your original submission matters so much: photographs, soil data, or a delineation report you didn’t include with the request cannot be added later to rescue the appeal.
